In Fig. 1, laser printer 100 has laser printer main body (below, be called printer main body) 100A.This laser printer 100 can be connected with networks such as computing machine or LAN separately, according to graphicinformation of sending or printing signal etc. by computing machine or network, the image by regulation form program after forming image (lettering) on the sheet material with its discharge.
In addition, sheet material processing apparatus 300 is configured in the top of printer main body 100A, its is being discharged to sheet material outside the machine from printer main body 100A in turn in the Quick Pulse System, afterwards, this sheet material is placed on the intermediate tray 15 as sheet material stacking portion, then, adjusts, after by the operation of every regulation sheet material being gathered, enterprising luggage is ordered at a position or a plurality of position of this sheet material.In addition, this sheet material processing apparatus 300 also can only be discharged sheet material and be placed on the discharge tray 50.
Below, the transport path of the sheet material S that the edge is transferred describes the structure of each several part among the printer main body 100A.
In printer main body 100A, in sheet feed cassette 200, be placed with many sheet material S, by various rollers, one by one separate in turn and carry uppermost sheet material S1.Afterwards, by printing signal by the regulation that computer or network provided, at first in image forming part 101, form the toner picture by so-called laser type image formation program, and toner looked like to be transferred to from sheet feed cassette 200 carry on the upper surface of the sheet material S that comes, then, fuser 120 heating by the downstream are also exerted pressure, with the permanent photographic fixing of described toner picture.
Then, image is by in the sheet material transport path of the roughly U word shape of the sheet material S of photographic fixing before arriving distributing roller 130, turned back and made image surface upset, like this, become at image surface under the state of downside, image is just drained into the outside in ventricumbent mode from printer main body 100A by the sheet material S of photographic fixing.
At this, can be corresponding to the turned position of the baffle plate 150 of printer main body 100A, select for example above-mentioned sheet material S to be discharged on (FD) discharge portion 125 that faces down on the top that is arranged on printer main body 100A by distributing roller 130, perhaps on the intermediate tray 15 of sheet material processing apparatus 300, wherein, the baffle plate 150 of printer main body 100A rotates according to the control signal that is arranged on the control part (not shown) on the printer main body 100A.
Below, the structure of sheet material processing apparatus 300 is described.
Fig. 2 is the enlarged drawing of sheet material processing apparatus 300.In Fig. 2, will from sheet material S that printer main body 100A discharge be directed to upper entrance guiding part 1 and bottom inlet guiding part 2 on one side, by top intermediate calender rolls 4 and bottom intermediate calender rolls 13 it is delivered to intermediate tray 15 on one side.In addition, be to be used to carry out the described bookbinding in back etc. handles middle stacking portion 14 by the part shown in the dotted line.
Like this, by top that is arranged on intermediate tray 15 and the distributing roller that sheet material S is discharged to intermediate tray 15, be that intermediate calender rolls is to 4,13, sheet material S is transported to intermediate tray 15, be transported to the sheet material S of intermediate tray 15, by carrying guiding part 6 to be directed to top exit roller 8 and bottom exit roller 17, after this, exit roller is carried 8,17 thus, immediately the sheet material rear end by intermediate calender rolls to after 4,13, the rear end letterweight plate 5 that fallen is pushed downwards, in this way, sheet material S is dropped on the intermediate tray 15.
Next, after this, the sheet material S that has fallen on the intermediate tray 15 is carried to the direction opposite with the sheet material throughput direction by the stripper rolls 7 as travel mechanism, like this, the rear end of sheet material S is connected to the benchmark wall that is used for the sheet material throughput direction of above-mentioned sheet material is adjusted, promptly adjust benchmark wall 11.In addition, exit roller can separate the 8, the 17th, and like this, when reverse feeding sheets S, exit roller is to 8,17 states that become separation.
Next, after on the sheet material throughput direction that has carried out sheet material S like this, adjusting, shown in Figure 3 be used for to sheet material S with the sheet material throughput direction width adjusting apparatus 30 adjusted of the position on the Width of quadrature mutually, direction from the position of readiness shown in the long and two-short dash line along the arrow indication moves to sheet material S and is connected to position on the Width benchmark wall 31, thereby carries out the adjustment action on the Width of sheet material S.
And, carry out adjustment action and adjustment on Width the action of such sheet material on the sheet material throughput direction repeatedly, in intermediate tray 15, stacked after the sheet material S of specified quantity, bind processing by clasp machine 32 in the sheet material end.After having carried out the bookbinding processing like this, to 8,17 stapled finished product is expelled to discharge tray shown in Figure 1 50 by exit roller.Referring to Fig. 2, control part can detect the full load conditions of sheet material S on discharge tray 50 by fully loaded check-out console 18.In addition, though in the present embodiment, control part by printer main body directly is illustrated the structure that sheet material processing apparatus 300 is controlled, but, also truing device (finisher) control part can be set on sheet material processing apparatus 300 1 sides, control by the truing device control part.Like this, the sheet material processing apparatus 300 that just needn't require printer main body to possess to install as attached configuration is the controllable function of prerequisite, as long as it possesses the control part that can satisfy the bottom line needs.
In addition, as shown in Figure 2, between adjustment benchmark wall 11 and stripper rolls 7, be provided with, to be used for guiding front end towards the sheet material S that adjusts 11 conveyings of benchmark wall as the last guiding part 12 of pinning mechanism's (pressing mechanism).Like this,, the rear end of the sheet material S that is returned by stripper rolls 7 foldbacks is guided to adjusting benchmark wall 11, make it butt and adjust benchmark wall 11 by guiding part on this 12.
